CABLE-FEELING MECHANISM.

' Specification of Letters Patent.

Patented Apr. 11, 1916.

Application filed May 12, 1911. Serial N 0. 626,656.

To all whom it may concern Be it known that I, FRANK L. SESSIONS, acitizen of the United States, residing at Golumbus, in the county ofFranklin and State of Ohio, have invented certain new and usefulImprovements in Cable-Reeling Mechanisms, of which the following is aspecification, reference being had therein to the actracks, but not withcurrent supply wires.

Therefore, when it is desired to operate a locomotive'in one .of thebranch entries or rooms the cable reeling mechanism is used to carry andto wind and unwind a conductor cable, the free end of which is securedto a stationary electric conductor, such as a trolley wire. In this waycurrent is carried from the stationary electric conductor to thelocomotive while it is operating over tracks in the branch entries androoms.

Theobject of this invention is to provide an improved cable reelmechanism compact in form and simple in construction andoperation,especially adapted for use with locomotives not originallydesigned for such operation.

In the accompanying drawings, which show the embodiment of my inventionwhich I now deem preferable, Figure 1 is a side view of a locomotivewith my improved cable reel mechanism attached. Fig. 2 is a plan view ofthe locomotive and cable reel mechanism. Fig. 3 is a cross sectionalelevation through the cable reel mechanism. Fig. 4 is aside elevation ofthe cable reel mechanism. 7

Referring to the drawings, A represents as a whole an electriclocomotive which is provided with the main frame 1, the axles 2,

a 2, the track wheels 3, 3 and the driving motween them is a bracket 6upon which the cable reel and the driving mechanism therefor aremounted.

represents as an entirety the cable reel, Wh1Cl1 1S mounted torotateabout a horizontal axis. The reel comprises a hollow drum 8, cableguiding and retaining side flanges 9, 9 and a hub 10 upon Which thedrum'8 is mounted. It will be observed that the drum 8 1s made up of twoseparate sections arranged on opposite sides of'a flange 11 on the hub.Through bolts 12, 12 serve to tie flange. I v 13 is a sleeve or quilltowhich'the hub 10 1s secured. The ball journal bearings-14 and 15 serveto rotatably suppo-rt'the quill and through the quill the whole reel.

vv16-is a horizontal shaft rotatably mounted near its center in abearing 17 secured in the quill l3 and at one end inthe bearing 18 onthe bracket 6. At the other end of the shaft there is secured a clutchelement 19 which lies within a cylindrical recess formed in the hub 10.20 and 21 represent two interengaging series of friction disks, thedisks of one series being connected to the clutch element 19jby means ofteeth 22, 22 and the disks of the other series being connected to thehub 10 by means of bolts 23, 23. 24 is a plate secured against rotationby means of- 'the bolts 23, 23 and pressed against the between thebearings 17 and 18. This worm wheel, engages with the worm 28 which ispositioned above it and which is mounted upon the horizontal motor shaft29.

30 represents the motor which is mounted upon the bracket 6. The motorshaft 29 is preferably provided with three ball journal bearings, 31, 32and- 33, arranged one at the motor end, one at one side of the worm andthe third at the other side of the worm. At the end of'the shaftopposite to the motor there is provided a ballthrust bearing 34. The twobearings 33 and 34 are supported on a head 35 which is secured to theupper section of the bracket 6 and which is prothe side plates and'thedrum'sections to this with the reel.

vided with a wire socket 41. At the end of the pivot pin 39 is a washer42 and a nut 43. Secured to the cylinder 40 is a spring at which engagesthe washer i2 and holds the cylinder in a position to provide goodelectrical contact with the bracket 37. The end of the cable is securedin the socket 4:1 and serves to cause the cylinder &0 to rotate The endof the supply conductor to the motors is secured in the socket 38.

Electrical connections are provided from the trolley wheel or'from thecable through a the main controller L9 and through the motors 4. 4:. Aconnection is also provided through the reel motor controller andthrough the reel motor so that when the controller 50 is in on positionthe motor 30 will be'continuously energi'zed'for rotation to tend toturn'the reel in the winding direction.

Assuming that the locomotive is in position with the cable unwound fromthe reel and is ready to start toward the fixed conductor, then themotor 30 is energizedand transmits power through the worm 28, the wheel27, the shaft 16 and the disk clutch to turn the reel inv the directionto wind the cable. The power of the motor is suflicient to maintain atension in the cable for all locomotive speeds. When it is desired tooperate the locomotive in the other direction, then the current may, ifdesired, be cut off fromthe motor 80 and the cable allowed to unwindagainst the resistance of the disk clutch, which serves as a frictionbrake. The worm Wheel engaging the worm serves to prevent the shaft fromrotating in the reverse direction. For short movements of the locomotivein forward and reverse directions it is not necessary to deenergize themotor 30 and in fact it will ordinarily be found advantageous to leaveit in operation continuously. In this way a continuous torque is appliedto the reel, whether the locomotive be moving in one direction, whetherit be standing'still, or whether it be moving in the other direction.

It will be observed that the mechanism which I have provided by myinvention is simple and entirely self-contained. By the provision ofsuitable cross-bars 5, 5 the mechanism may be attached to anylocomotive, even though not originally intended for cable reeloperation.

'VVhat I claim is: I

In a cable reeling mechanism, the CO1T- bination of a supportingframework, a cable reel provided at one side with anaXia-l hollowtrunnion rotatably mounted in the framework, the reel being supportedsolely by the trunnion and having an axial chamoer within its outlineswhich is open at the side opposite the trunnion, an independentlyrotatable shaft extending through the hollow trunnion into the axialchamber, means connected to the shaft at its outer end for driving it,and a friction clutch in the said chamber for connecting the inner endof the shaft with the reel, parts of the clutch being removable throughthe said open end of the FRANK L. sessions.
